    Abstract

    A new average flow model to analyze the lubrication characteristics of mechanical seals with parallel sealing faces is proposed. The present model determines the flow factors considering the side leakage under the operating condition equivalent to that in the mechanical seal. The correction factor for the expected hydrodynamic pressure generated by the relative motion of rough surfaces is also defined. The results are compared with those based on the Patir's average flow model and show that the present model can be effective for the analysis of the lubrication characteristics of mechanical seals with parallel sealing faces.
